Modulation of vocal pitch control through high-definition transcranial direct current stimulation of the left ventral motor cortex.

Neural interactions between sensorimotor integration mechanisms play critical roles in voice motor control. We investigated how high-definition transcranial direct current stimulation (HD-tDCS) of the left ventral motor cortex modulates neural mechanisms of sensorimotor integration during voice motor control. HD-tDCS was performed during speech vowel production in an altered auditory feedback (AAF) paradigm in response to upward and downward pitch-shift stimuli.

Toward a "smart" nightstand prototype: an examination of nightstand table contents and preferences.

Objective: Two studies were conducted to obtain an understanding of the types of items seniors keep in their nightstands and to understand how users feel about the possibility of "smart" furniture.

Background: To enable aging in place and universal design, it is vital to understand the needs of a broad range of aging individuals, especially since there is little research on nightstand usage and design.

Methods: Study 1 allowed for the development of a structured inventory of nightstand use today in assisted living and rehabilitation facilities.
